Safety operation requirements of injection molding machine
The operator must be familiar with and understand the function and function of the switch buttons on the equipment operation panel, and operate in strict accordance with the operating rules.
Operational requirements
1. Before the machine heats up and starts production, open the cooling water valve and observe whether the water channel is unblocked.
2. Close the power switch on the side of the control box, turn on the internal power supply, and press the motor start button on the panel to start the oil pump motor.
3. For the machine that is used for the first time and has not been used for a long time, after the oil pump is started, it must be run for a few minutes before starting to operate.
4. Turn on the barrel heating switch, turn on the electric heating power, adjust the thermostatic nozzle and temperature controller on the door of the box, set the temperature, observe the current of the ammeter, and judge the quality of the electric heating coil.
5. The test run should be carried out from manual to semi-automatic to fully automatic. At the same time, check whether the important fastening bolts are loose, and stop immediately if any abnormality is found. After confirming that it is normal or troubleshooting, then carry out the test run.
6. The barrel should be cleaned when the uhmw machining is stopped or when the material is changed. The cleaning should be carried out under the condition that the barrel is heated. When the cleaning is completed, the heating switch should be turned off immediately. The cleaning is particularly important for the processing of easily decomposable plastics.
note:
① The injection seat must be returned when cleaning
② The temperature setting when the two raw materials alternate should be adjusted according to the requirements of high melting materials
③ Wash the decomposed materials with polystyrene
7. When machining uhmw stops, first turn the action operation switch to the manual position, and other action switches
Put it in the OO position, turn the barrel heating switch to OFF, press the motor stop button
Turn off the oil pump motor, and finally turn off the power switch to end the work.
